@Surendar - Please make sure you always provide the detail explanation with clear examples, which would help OS community to help / guide you.

If my understanding is correct you would like to have list of operations to be done from your OS development
1. Storing data containing RAILWAY Timing Information
2. Send real time statuses to the RAILWAY Stations

If above is the case - you must follow list of workflow processes
Storing of data in your system / integrate a solution thru XML sources into your system (SOAP / REST) / import data
Create a workflow --> Apply conditions "Something like triggers" / create a timing trigger which will keep sending the notice --> As and when your record or status or timings gets updated --> Send mails / notice / SMS to the stations
